Patented July 29, 1930 PATENT OFFICE EDWARD s. Pannier TOPEKA, KANsAs HUMIDIFIER FOR INTERNALCOMBUSTION ENGINES i Application filed November 8. 1927. SerialNo. 2313556.

My invention relates to a means'to humidify the fuel for internal combustion engines. Theobject ofgmy invention is to provide a means that will inject steam or vapor from the radiator into the intake manifold of an internal combustion engine, whereby the mileage is increased with a normal fuel consumption through the medium of my invention herein set forth.

A further object of my invention is to provide a valve and controlling means therefor operative from the instrument board of the vehicle, the valve to control the flow through the pipe connecting means of the radiator to the coil.

'A still further object of my invention is to provide means to prevent the water from ontering the pipe conveying the steam or vapor to the manifold when the radiator is being 3 filled or the water therein unduly agitated.

A still further object of my invention is to provide a housing means to attach the coil to the exhaust manifold and simultaneously protect the coil from external exposure.

A still further object of my invention is to provide a bafile means in the pipe to distribute or break up drops of water, should they pass therethrough.

These and other objects will be hereinafter more fully described.

Referring to the drawings:

'Fig. 1 is aside View representing an internal combustion engine and its radiator.

Fig. 2 is a fragmentary front end'view of the engine parts removed for convenience of illustration. 7

Fig. 3 is an enlarged plan view of the hood on the end of the pipe positioned in the radiator.

Fig. 4. is an elevation of Fig. 1;

My ZlIIVQIItiOIlICOIlSiStS of a pipe 1 extending through the radiator 2 and having an upward bend as at 3, by which means the top thereof is positioned above the water line of the radiator. i,;Positioned onthe upper endof thepipe is a hooda, cylindrical in form and having an aperture 5rin the bottom thereof to receive the pipe snugly. On the upperend Q of the pipe, concealed by the hood, are legs 6 functioning as spacing means for thetop or closed end of the hoodfrom the end of the pipe; the said hood has a plurality of aper- Fig. l and also a plurality of apertures 8 annularly arranged in, the bottom adjacent the pipe, the saidaperturesfunction as means by whichjthe steam orvapor rising from the water mayenter and be. drawn through the pipe and injected intothe intake manifold 13; the apertures in the bottom function as a drain for condensation or water that may enter through the side apertures when filling rod 10 connected thereto and extending rearward through the instrument board 11, and

having a handle 12 on theouter endthereof as means by which the valve may be turned by the operator of the vehicle, opening or closing the valve.

The horizontal portion of the said pipe, as at A, extends rearward and being coiled as at B is means by which a greater area ofthe pipe length may be bound or positioned closely to the exhaust manifold 13 as shown inFigure 1. The outer end of the coil has a transversely positioned bend entering the neck C between the carburetor D and the manifold, by which means the steam or vapor is' injected simultaneously with the gas fromthe 'tures 7 inthe sidewalls thereof as shownin j carburetor into the cylinders of the engine 14. e

its component. parts 'As a means to preheat thejcoil-of'thepipep a housing '15 is provided as an enclosure for the said coil and bindinglmeans therefor. snugly against the side of said "manifold.

The said housing is securely attached to the manifold by means of straps 16 and .17, the ends of which are attached by bolts 18 and 19. Centrally positioned and laterally extending from the housing is a portion thereof as at F functioning as a guard for a downward extension of the coil as shown in Fig. 1. It will be understood that the peripheral edge of the housing engages snugly" on said manifold and being concaved sufli'ci'ent to receive the pipe coil. Positioned diametricallyin the coiled portion of the pipe is a plurality of pins 20, functioning as a bafile or separating means for drops ofwayter. passingthrough the pipe, so'that the drops may be more easily vaporized prior to entering the manifold. In Fig. 6 is shown the lower end of the pins aligned "in close] prtxrmity longitudinally withthe pipe and spaced apart si milar' to that in=-Fi- 5', the" pins being angled in opposite d ire'ctlons alternately, While I have stated that the pins are positioned inthe coil", they may be placed as desired along the pipe in groupsor'equally spaced along the pipe, and being positioned with the lower ends close alignment is means to insure contact with the drops passing along the lower side of the pipe, as would naturally be the case. i

To operate'niyinvention it is-preferahle' to c'lose the Valve when startingtheengi'ne, and as soon as the eng'ineis properly heated to its normal running temperaturethe' Va'lVe may r h-t e per phe W h f, the t n 1 then be opened'partiallyor entirely, at which time the Vapor-is introducedregularl with the gasniilttnre as-it enters the cylinders of the en ine and the Vapor thus applied is beneficial intending to prevent carbon" deposits, aswellas increasing the mileage of the gas consumption through the mechanism as design'ed. I t Such other modifications may be: employed as lie within the scope of the appended claim. Having fully described my'invention, what I claim asnew and desire to secure by Letters Patent is: V g
